How do you increase the number of coins you can protect and the duration of protection? Or is it not possible? Is the number strictly guild based? My brother's circle 20 Thief can protect 3, the same as a Ranger I asked that had 500+ perception and a ton more stats. I can protect 4 and am wondering how I get one more than the Ranger.

I can protect 7 coins
